    TORONTO, Jan 28 (Reuters) - The Canadian dollar weakened to
its lowest level in more than three weeks against its U.S.
counterpart on Friday as recent volatility in global financial
markets offset higher oil prices.
    The loonie        was trading 0.4% lower at 1.2794 to the
greenback, or 78.16 U.S. cents, after touching its weakest level
since Jan. 6 at 1.2796.
    For the week, the currency was down 1.7%, its biggest weekly
decline since August 2021.
    "Near-term risks are tilting a bit lower for the currency
amid soft risk appetite and a long wait for the March BoC
decision," strategists at Scotiabank, including Shaun Osborne,
said in a note.        
    Canada is a major producer of commodities, including oil, so
the loonie tends to be sensitive to investor sentiment.
    Wall Street's main indexes turned higher on Friday, at the
end of a week marked by wild gyrations on worries about
aggressive rate hikes by the Federal Reserve and rising tensions
between Western powers and Russia.             
    The Bank of Canada surprised some investors on Wednesday by
choosing not to hike its benchmark interest rate, which sits at
a record low of 0.25%. Its next policy decision is due on March
2.
    With the Fed turning more hawkish, the gap between Canada's
2-year bond yield and its U.S. equivalent fell on Friday to its
lowest level since April 2021 at about 7 basis points in favor
of the Canadian bond.
    Oil prices notched their highest levels in over seven years
as ongoing global political turmoil fanned concerns over tight
supply. U.S. crude        prices settled 0.2% higher at $86.82 a
barrel.             
    Data showed Canada's budget deficit shrinking in the first
eight months of fiscal 2021/22.                     
    Canadian government bond yields eased across the curve, with
the 10-year             down 2.6 basis points at 1.751%.
